Ultherapy（以Ulthera儀器進行的皮膚療程之名稱）是一種非手術緊膚HIFU療程，運用聚焦超聲波科技，繞過表皮肌膚，並把能量加熱至65-70℃且凝結成大量極微細的熱點，以3段波長 (4.5mm、3mm、1.5mm) 精確地直達肌腱膜、真皮膚及真皮淺層：於3mm的真皮層，刺激膠原蛋白的生長，令底層肌膚逐漸收緊；而4.5mm的肌底下的肌腱膜(SMAS)，強化肌膜承托力,令已鬆弛的肌肉提升及收緊，媲美手術拉皮效果；而1.5mm的真皮淺層，改善眼部周邊幼嫩肌膚。

Ultherapy® uses microfocused ultrasound to generate a thermal effect under the skin. This effect essentially jump-starts your body’s own process to create fresh, new collagen.

As a natural protein, collagen works to give skin its youthfulness by keeping it firm and toned. As we age, collagen breaks down, and the result is a loss of skin strength and elasticity.
